TL;DR – In my last article, I wrote about the steps it takes to build a Docker image with cross-compiled native libraries for arm-hf/arm32/Raspbian/RaspberryPi and .NET Core 2.0.0 DLLs compiled for linux-arm. However it takes too many manual steps upon running your own container. A better practice is to build a Dockerfile which you can download.

How to get started?

Run this on your dev machine, not your target Raspberry Pi. This is because the Docker image is based upon Debian 8 (jessie) x86-64 GNU/Linux. This is the environment needed to run the RPiToolchain as well as the .NET Core 2.0.0 SDK.

As a result of the cross-compilation and .NET Core 2.0.0 compilation, you get a tar ball which you can copy onto your target Raspberry Pi. The cleanest way to do so is by mounting a host directory onto your container before running it. Then copy the iot-edge-rpi.tar.gz to /mnt.

Copy iot-edge-rpi.tar.gz to your target Raspberry Pi. Easiest way is to use SCP.
